(7) When continuous trace is used, do not enable user interrupt by the INTERRUPT command
The profile function internally breaks user program execution, collects the measured data, and
re-executes the user program.
Since the function also counts when the measured item is generated at break or re-execution,
an error will be included in the measured profile value.
The measured value of this function should be the target.

An internal I/O trace cannot be made with the Step In command.
The LDTLB instruction and internal I/O trace cannot be performed with the Step Over
